title: The Association of Sleep Duration, Mental Health, and Health Risk Behaviors among U.S. Afghanistan/Iraq Era Veterans.
abstract: OBJECTIVE
  Short and long sleep duration have been linked with higher rates of comorbid medical and mental health issues, as well as increased mortality. The current study examined the association between sleep duration, mental health problems, and health risk behaviors in a large sample of U.S. Afghanistan/Iraq era veterans.
  
  
  METHODS
  NA.
  
  
  METHODS
  Mid-Atlantic VA Medical Center(s).
  
  
  METHODS
  The sample (N = 1,640) included 20% women (n = 333) and had an average age of 37 years (SD = 10.0).
  
  
  METHODS
  NA.
  
  
  RESULTS
  Results from logistic regression analyses that included age, minority status, gender, military rank, number of deployments, combat exposure, and health risk behaviors as covariates indicated that very short sleep duration (≤ 5 h of sleep) and long sleep duration (≥ 9 h) were each associated with increased odds of current post traumatic stress disorder (PTSD), major depressive disorder (MDD), and smoking; while poor sleep quality was associated with PTSD, panic disorder (PD), MDD, suicidal ideation (SI), and risky drinking.
  
  
  CONCLUSIONS
  Sleep duration may be an important marker for psychiatric and health risk behavior problems, and our results suggest that clinical assessment of sleep disturbance in this veteran group is warranted to assess for both short and long sleep.
